Explanation:
Let's solve the problem by using conservation of momentum:
m1 u1 + m2 u2 = m1 v1 + m2 v2
where:
m1 = 3.5 g is the mass of the blue marble
m2= 1.2 g is the mass of the red marble
u1 = 15 cm/s is the initial velocity of the blue marble
u2 = 3.5 cm/s is the initial velocity of the red marble
v1 = 5.5 cm/s is the final velocity of the blue marble
We can find the final velocity of the red marble by re-arranging the equation and solving for v2 :
v2 = 1/m²(m1 u1 + m2 u2 - m1 v1)=
=1/1.2(3.5×15+1.2×3.5−3.5×5.5 )=31cm/s
If everything else is held constant ... the substance from which
the conductor is formed, its cross-sectional area, its temperature
everywhere along its length ... then yes, its resistance will be
directly proportional to its length.
This shifts chemical equilibria toward the products or reactants, which can be determined by studying the reaction and deciding whether it is endothermic or exothermic....
Answer:
Acceleration is 8.45 and the tension is 2.775
Explanation:
Lets apply the equation F=ma for vertical block,
5-T= 0.5a
foe the frictional force acting on the object,
f=0.11×5 (consider equation no.1)
=0.55N
Applying F=ma for the block which is on surface,
T-0.55=0.5a (consider as equation no.2)
no.1=no.2
5.55=2T
T=2.775
by equation no.1,
4.225=0.5a
a=8.45
